Office of River Protection

The U.S. Department of Energy’s (DOE) Hanford Site in southeast Washington State is home to 56 million gallons of chemical and radioactive waste stored in underground tanks, the result of more than four decades of plutonium production. The Offi­ce of River Protection (ORP) is responsible for the retrieval, treatment, and disposal of this waste in a safe, effi­cient manner. The River Protection Project is the largest and most complex environmental remediation project in the nation.
